Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation01:21

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...
Peripheral Artery Disease I: Introduction01:30

Peripheral Artery Disease I: Introduction

Peripheral artery disease (PAD) predominantly results from atherosclerosis, which involves the accumulation of fatty deposits, or plaques, within the walls of arteries. This causes them to narrow and harden, significantly reducing blood flow. PAD predominantly affects the legs, particularly the arteries supplying the thighs and calves. In rare cases, it may involve other arteries, including those in the arms.Etiology of PAD:The principal cause of PAD is atherosclerosis, which results from fatty...

Peripheral Artery Disease IV: Nursing Management

The nursing management of a patient with peripheral artery disease (PAD) begins with a thorough assessment of the patient’s health history and clinical manifestations.AssessmentHealth History: Evaluate the patient’s history of hypertension, hyperlipidemia, family history of cardiovascular issues, and lifestyle factors such as dietary patterns, smoking, and physical activity.Physical Examination:Assess the affected extremity for decreased or absent peripheral pulses, temperature changes,...
Peripheral Artery Disease III: Interprofessional Care01:27

Peripheral Artery Disease III: Interprofessional Care

Peripheral Artery Disease (PAD) is characterized by narrowed arteries that diminish blood flow to the extremities. Effective management of PAD requires an interprofessional approach involving various healthcare professionals. The critical aspects of interprofessional care for PAD patients focus on risk factor modification, drug therapy, exercise therapy, nutrition therapy, critical limb ischemia care, and interventional radiology and surgical procedures.The primary treatment goal for PAD...
Peripheral Artery Disease V: Postoperative Nursing Management01:23

Peripheral Artery Disease V: Postoperative Nursing Management

During the postoperative period, it is crucial to focus on maintaining circulation, identifying and managing potential complications, and planning for discharge.Nursing AssessmentVital signs monitoring: Regularly monitor vital signs, including blood pressure, heart rate, respiratory rate, and temperature, to detect early signs of complications such as bleeding and infection.Circulation assessment: Monitor pulses, perform Doppler assessments, and check capillary refill, color, temperature, and...
Atherosclerosis II: Clinical Manifestations and Diagnostic Tests01:27

Atherosclerosis II: Clinical Manifestations and Diagnostic Tests

Atherosclerosis is a progressive disorder that leads to the thickening and narrowing of arterial walls due to plaque buildup. This condition can cause various symptoms depending on the arteries affected:Coronary Artery Disease (CAD): This condition affects the coronary arteries and may lead to chest pain (angina), shortness of breath (dyspnea), heart attacks, and other heart disease symptoms.Cerebrovascular Disease: This affects blood flow to the brain, causing transient ischemic attacks (TIAs)...

Summary

Peripheral arterial disease (PAD) patients exhibit altered ankle kinematics during gait, even before claudication pain onset. These gait changes in the ankle joint are significant, unlike hip and knee joint movements.

Area of Science:

  • Biomechanics
  • Orthopedics
  • Vascular Surgery

Background:

  • Peripheral arterial disease (PAD) is a leading cause of impaired walking ability due to claudication.
  • Understanding gait alterations in PAD is crucial for managing ambulatory dysfunction.

Purpose of the Study:

  • To characterize the kinematic gait patterns of patients with PAD using advanced biomechanical analysis.
  • To test the hypothesis that claudicating patients have altered kinematic gait patterns compared to healthy controls.

Main Methods:

  • Evaluated kinematic parameters (hip, knee, ankle joint angles) in 14 PAD patients and 5 healthy controls during gait.
  • Compared joint angles during stance phase, including range of motion and timing of motion, before and after claudication onset.

Main Results:

  • PAD patients showed significantly greater ankle plantar flexion and range of motion during stance.
  • Time to maximum ankle plantar flexion was shorter, and time to maximum dorsiflexion was longer in PAD patients.
  • No significant kinematic differences were found in the hip and knee joints between PAD patients and controls.

Conclusions:

  • PAD patients exhibit significant ankle joint gait alterations prior to claudication pain.
  • Hip and knee joint kinematics do not differ between PAD patients and controls.
  • Further research is needed to confirm findings and explore disease progression and treatment effects.
